Obfuscate/make your JS code explode in size using only 6 characters.
The characters that this obfuscator will use are ()[]+!

This is a work in progress.
Demo coming soon =)

var script = "alert('hello!');";
var evil = evilize(script);

console.log(evil);
eval(evil);

ToDo: Evilizing of strings works, numbers don't.

Note: This obfuscator doesn't strive to use the least characters as possible. It strived mostly to be the least programming work. This means it really is explosive.

Q: This isn't possible!
A: Yet it is! We can generate a base character set using only these few characters, by making them output the values (false,true,undefined,NaN,Infinity). These are enough to create a full charset.

Q: Can I obfuscate whole documents with this?
A: Theoretically you can, but practically you'll probably run out of RAM

Q: Can I use this as a javascript compressor?
A: Obviously not.

Q: Then what's the use?
A: Security through obscurity? Other than that, nothing that I can think of!
